Application filed November 10, 1914. Serial No. 871,317.

port the staging at various positions of adj ustment vertically of theroof, as the work progresses, the clamp being disposed for detachableengagement with the shingles of the roof.

The invention has as its primary object to provide a clamp which may bereadily arranged in operative position upon the roof and which may beremoved with equal facility, and wherein the clamp is so constructedthat injury to the shingles of the roof will be obviated.

A further object of the invention is to provide an improved clamp ofthis character which may be used upon any shingle roof as commonlyconstructed, and wherein the use of nails or other fastening devicessuch as would perforate the roof, is dis pensed with. And the inventionhas as a still further object to provide an improved clamp of thischaracter which will be exceedingly simple in construction andthoroughly efficient in operation.

lVith these and other objects in view, my invention will be more fullydescribed, illus trated in the accompanying drawings and thenspecifically pointed out in the claim which is attached to and forms apart of this application.

Figure 1 is a side elevation showing my improved clamp in position upona roof, the portion of the roof shown being conventionally illustrated,Fig. 2 is a horizontal sectional view of the clamp showing the saidclamp in engagement with the butt of a shingle, and Fig. 3 is a top planview of the clamp.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawing by the samereference characters.

clamp which may be readily attached to the butt or free end of a shingleafter it has been secured in proper position upon a roof, and soconstructed as to support the staging. Accordingly, my improved clampincludes a relatively thin base or body portion indicated at 10 in thedrawings which is preferably formed of a piece of suitable sheet metaland which may be readily inserted beneath the free end of the shingle asshown in Figs. 1 and 2 of the drawing. Adjacent one extremity, the base10 is bent upon itself to provide an angularly disposed upstanding arm11, the purpose of which will presently appear. It will be understoodthat the base 10 may be of any desired length or width and that thedimensions of the arm 11 may also be varied, as desired.

Secured to the body portion 10 intermediate its ends and substantiallymedially thereof is a bracket 12, which at one on tremity, may beconnected with the body portion in any suitable manner as by rivets 13.Intermediate its ends, the bracket 12 is formed with an upstanding shank14, which extends perpendicularly from the base 10 at substantiallyright angles thereto and which at its outer extremity, terminates in alongitudinally extending and horizontally arranged arm 15, the arm 15being arranged substantially parallel with the base 10, and having itsfree end terminating in substantial alinement with the adjacent end ofthe base.

Arranged upon the outer free extremity of the arm 15 and adjustablethereon toward or away from the base 10 is a set screw, the screwthreaded shank 16 of which engages within a correspondingly threadedbore formed in the arm, the shank 16 being provided with a suitable head17. Swiveled upon the shank 16 at its opposite extremity is a clampingdisk or foot 18.

Loosely mounted for rotative movement upon the bracket 12 is adetachable clamping plate 19. The detachable clamping plate 19 ispreferably formed of sheet metal and is of a width substantially equalto that of the base 10, the said plate adjacent one extremity having anopening 20 medially formed therein to freely receive the shank 14 of thebracket by which it is normally retained in proper position. It will beobserved that when the plate is in operative position the outer free endis in substantial alinement with the adjacent end of the base 10 anddisposed for engagement by the foot 18 of the set screw. The opening 20it will be observed is suificiently large to permit the plate 19 to beturned around out of the way when the base member 10 is being forcedbeneath the shingles of the roof.

For convenience, I have conventionally illustrated in Fig. 1 of thedrawings, a portion of a roof with one of my improved clamps in positionthereon in order that the application and use of. the. invention mightbe entirely clear. As. therein illustrated, the extremity of the base 10opposite the arm 11 is inserted beneath the free end or butt of ,ashingle with the clamping plate 19 bearing over theend of the saidshingle, and in this connection, it is to be observed that the shank 14-of the bracket 12 is disposed to limit the clamp in its inward movementupon the free end of the shingle. The set screw carried by the bracket12 is then operated, to force the clamping plate 19 down into secureengagement with the free end of the shingle to thus firmly secure theclamp in position.

It is to be understood. that in practical use, a pair of my improvedclamps is to be employed and attached to a roof in the manher justdescribed in longitudinal spaced relation thereon, or in other words,one of the clamps may be attached to the roof adjacent one side edgethereof while another clamp may be attached adjacent the opposite sideedge of the roof. When thus arranged, it will beobserved that the arms11 will project upwardly to receive and retain a cross-piece or stagingstrip 21.

From the preceding description, it will be seen that the staging 21 maybe readily positioned on the clamps in the manner set forth while saidclamps and staging may be easily adjusted vertically upon the roof asthe work progresses. It will further be seen that I provide a clampwhich will not injure the shingles of the roof through being attachedthereto and wherein no fastening devlces are employed such as wouldperforate the shingles. Owing'to the presence bracket including a baseplate having its rear end bent' upwardly at right angles thereto to forma vertically disposed arm adapted to support a staging member, a'

standard secured to the base plate inspaced relation to the arm andhaving a horizontally disposed portion spaced from the plate andpro'videdwith a threaded opening, a.

clamping plate of substantially the same width as the base plate looselyfitted over the standard and having a relatively large opening thereinto accommodate the standard and permit rotative movement of the platewith respect to said standard, a clamp screw threaded in the opening inthe horizontal portion of the standard and having its upper end providedwith a head, a clamping disk swiveled on the lower end of the screw andindependent of and coacting with the clamping plate, to clamp a shinglebetween the base plate and clamping'plate when the screw is adjusted,the free end of the arm extending upwardly in a straight line above thestaging member to permit the staging member to be moved vertically ofthe arm when placing said staging member on or removing the stagingmember from the base plate.

In testimony whereof I aflix my signature in presence of two witnesses.
